lissus, Zizyphinus [ Calliostoma zizyphinum (Linnaeus, 1758) ] ( Figures 5H, I )

1889b: 78 [XXXVII: 888]—available name

Type material. MCZR–M–11578 —3 sh “ Trochus (Zizyphinus) zizyphinus Lin. var. laevigata Mari d’Inghilterra !”

Type locality. Described from Seas of England.

Remarks. Recorded by MolluscaBase (2018) as taxon inquirendum. Name proposed for Trochus laevigatus Gmelin, 1791 sensu Sowerby and other British Authors, considered as a distinct species, and utilized to distinguish the Atlantic specimens from the Mediterranean ones of Trochus zizyphinus Linnaeus, 1758 . We therefore keep it in the synonymy of Calliostoma zizyphinum (Linnaeus, 1758) [new synonymy], pending a revision of the group to assess the status of the Mediterranean v. Atlantic populations.
